I know AFR ideal is stoich 14.7, fuel trims, maf voltage, vvt, etc.. I have no idea. I just noticed when WRB5titch shifts his afr doesn't spike like mine. http://datazap.me/u/target70/stock-tune?log=0&data=1

When you let off your afrs will spike. I can't see your graph on the phone but that may be what's happening.

They spike when you let off because there's suddenly no fuel coming in and it takes a certain, small amount of time for the computer to adjust down the air coming in, correct?

Yes, when you let off the gas the injectors are switched off, so naturally the AFR will spike super high because there's no fuel going into the engine.

I feel the exhaust mods open up the top end so it doesn't drop off so much and provides for a smoother curve.

What gas are you using?

94oct. 10 percent ethanol

Nice! We got 93 octane down here. Think I can expect that with Open Flash header, drop in filter, esc 1.5 and OTS tune?
Just dynoed at 174 with stage one and filter. Waiting on header

I could understand that. I just wasn't sure why mine was maxing out:


and WRB5titch was only at 13 and 15.27 max

Nothing to worry about. His night not go as high because the ESC keeps running a split second after WOT changing the off throttle Afr. That's just a random guess.

As magicbobert have stated above, when you let off the gas while in gear the fuel is shut off until you reach idling speed. It is normal. Even the stock map does this, don't worry.

If anything you could call it the purging stage, where it burns any left over fuel in the cylinder

1.5 Dump Upgrade log as promised.

How long does it take to condition the batteries?
I.e. how many wot pulls before felt a significant change in power

[Gary in NJ]

It takes between 25 to 50 engagements to fully condition the dump pack.

[shif7i7down]

So technically you could fully condition the batteries in one day?

Yes. Technically.
